For enabling push notification on pushd server, you need to get a file with .p12 extension and .cer certificate file. For pushd to work you need to generate a .pem file and give its path in push configuration(`/etc/pushd/pushd.conf`).

We need to generate 2 pem files one called apns-cert.pem (generated from .cer file) and the other called apns-key.pem (generated from .p12 file).

To generate .pem file use openssl command, with the format below:

openssl pkcs12 -in YOUR_KEY.p12 -out apns-key.pem -nodes

NOTE: it may ask you for the password, enter the given password by whom that gave you the p12 file.

-in set your input file name and -out sets your output file name which will be generated.

And now generate the key pem file:

openssl x509 -in cert.cer -inform DER -outform PEM -out apns-cert.pem

Restart the pushd and check for any error in /var/log/pushd.

#pushd #openssl #p12 #cer #pem #push
